The mean Hebrew calendar year is 365
days 5 hours 55 minutes and 25+25/57
seconds long (365.2468 days) -
computed as the molad/monthly interval
of 29.530594 days × 235 months in a
19-year metonic cycle ÷ 19 years per
cycle. As the present-era mean
northward equinoctal year is 365 days
5 hours 49 minutes 19 seconds long
(365.2424 days), the Hebrew calendar
has a "seasonal drift" in relation to
the tropical year of about a day every
224 years.

One Purim morning, at the crack of dawn, Rav Chaim Sonnenfeld appeared at the house of his rebbe, the Gaon Rav Yehoshua Leib Diskin, carrying a basket of shalach manos. His rebbe asked him why he had come so early.... Rav Chaim answered, "When I was a child I became deathly ill, and my parents added 'Yosef' to my name. I then became 'Yosef Chaim', which is numerically equivalent to the word זריז‎, 'zealous'. Since Hashem has granted me life, I am zealous to attend to the mitzvos as quickly as possible...."
